What is Independence Day?
1.
An American holiday, that occurs every July 4th.
"Today, we celebrate our Independence day!"-Bill Pullman, Independence Day
2.
A movie that shows what is needed for all people to set aside their differences and work together: a massive alien invasion with laser shooting vagina spaceships.
And should we win the day, the Fourth of July will no longer be known as an American holiday, but as the day the world declared in one voice: "We will not go quietly into the night!" We will not vanish without a fight! We're going to live on! We're going to survive! Today we celebrate our Independence Day! -President Thomas Whitmore

The day that you realize that you are so over your ex boy/girlfriend. You don't even want to use them for a booty call.
I was hanging out with him and realized that it was my independence day, i no longer had any romantic or sexual feelings for him anymore. I was relieved.
